CVE-2012-2137

Published: 18 June 2012

Buffer overflow in virt/kvm/irq_comm.c in the KVM subsystem in the Linux kernel before 3.2.24 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to Message Signaled Interrupts (MSI), irq routing entries, and an incorrect check by the setup_routing_entry function before invoking the kvm_set_irq function.

From the Ubuntu security team

A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual Machine) subsystem handled MSI (Message Signaled Interrupts). A local unprivileged user could exploit this flaw to cause a denial of service or potentially elevate privileges.
